Description of the invention (1 5 10 15 Printed by the Consumer Cooperative of Intellectual Property Bureau of the Ministry of Economic Affairs 20 The present invention relates to a driving method for a plasma display. More particularly, the present invention relates to a method for shortening an address. The technology of the cycle. Plasma display (PD) devices have good sharpness, thinness and can be made with large screens and high-speed displays because it generates its own light. Therefore, it is a good replacement for CRT displays. Figure 1 It is a diagram showing the basic structure of a PD device. As shown in Fig. 1, in a plasma display panel (PDP) 10, the X electrode (the first electrode: the sustain electrode) X1, X2, ... The Y electrodes (the second electrode: the scanning electrode) ΥΙ, Υ2 ^^ are alternately arranged next to each other, and the address electrodes (the third electrode) A1, A2, ... are in the direction with the χ and Υ electrodes.

Invention Explanation (2) A graphical representation of the sequence of actions. The discharge of a plasma display has only two states, namely, on and off, and the display level is represented by the number of times the light is emitted. Therefore, a frame corresponding to a display is divided into several sub-frames, as shown in Shown in Figure 2. Each picture contains a reset cycle, an address 5 cycle, and a sustain discharge cycle (sustain cycle). In the reset cycle, a cell is turned on and off regardless of whether the cell was turned on or off in the previous picture. The action that all cells are in a homogeneous state is performed, for example, a state in which wall charges are eliminated or wall charges are formed uniformly. In the address cycle, a selective discharge (address discharge) is performed, and according to the Displaying data to determine the on or off state of a cell and the wall charge required to perform the discharge of light emission in the next sustain period are formed in an on state cell. During the sustain period, the discharge is repeatedly performed in order to emit light from the cells placed in the on state during the address period. The length of the sustain period, that is, the number of times the light is emitted is different in each picture, and the displayed level can be set by 15 to set the number of times the light is emitted. For example, 1: 2: 4: 8 ..., and the combination time Figure 埸 俾 is represented by this level for each cell emitting light. Fig. 3 is a waveform diagram showing an example of a conventional driving method of a plasma display panel. As shown in the figure, in the reset period, a pulse having a voltage Vw larger than the start voltage of the discharge, for example, 300V, is applied to the X20 electrode. The application of this pulse caused the discharge of each cell, regardless of whether the cell was turned on or off in the previous figure 埸, and the wall charge was formed. When this pulse is removed, the discharge occurs again by the voltage of the wall charges themselves. However, since there is no difference in potential between the electrodes, the space charge generated by the discharge is neutralized and there is no wall charge. The homogeneous state below is on page 5.

Invention Description (3) Realization. Although almost all charges are neutralized, a small amount of ions or metastable atoms are still in the discharge space. One possible situation is that, in the absence of a fault, these residual charges are used as the pilot charge that causes the next address discharge. Usually, this system is called the guiding effect or the starting effect. In the address period, a scan pulse is sequentially applied to the γ electrode and a single address pulse (address signal) is applied to the address electrode of the cell to be turned on on the display line, causing discharge. This discharge propagates to the X electrode side and 2 charges are formed between the χ electrode and the γ electrode. This scan is performed on the display line of =. Next, a sustaining pulse having a voltage Vs (approximately 170 ν) is repeatedly applied to the X electrode and the γ electric current in the sustaining cycle system. When the sustaining pulses are applied, a wall electric discharge is formed during the off-state period. , Because the voltage of the wall charges is superimposed on the two-dimensional period == and the total voltage exceeds the discharge starting voltage. At the address gate J 肀, cells that do not have wall charges will not discharge. The basic structure and action of the "_" is described above: Examples of various changes are proposed. In one of these changes, for example: several pictures with the same number of light emission times are set at the second to make the animation display smooth. In another-variation, the dagger is executed in the field. In another change, the repetition will be performed in the next time, and the 6th time you can only reset it. The reset is not performed in all the cells. The second image is performed in the previous cell that was turned on. At another address 1 = use: the qualitative wall charge is left in the reset action and the bit fr is eliminated to select the cell that is to be turned off and the wall in the address action is eliminated. In another variation, 'Removal pulses are removed by applying-voltage.

Description of the Invention (4) Between the X electrode and the γ electrode, the desired amount of charge to be used in the address operation is left. In addition, the applicant of this case disclosed a structure in Japanese Unexamined Patent Publication (Kokai) No. 6_314〇78, in which the voltage of the reset pulse is designed to rise to an obtuse angle waveform so that the 5 voltage gradually As a result, the homogeneous charge remains on the entire surface, and in Japanese Unexamined Patent Publication (Kokai) No. 2000-75835, it is also revealed that the rise and fall of the reset pulse are designed to have a waveform with a progressive slope. Furthermore, the applicant of this case disclosed the so-called ALIS plasma display device in EP 0 762 373 A2. In this device, a display line 10 is formed on each of the X electrodes and the Y electrodes. The gap between the Y electrodes and the X electrodes on both sides is doubled without changing the number of the X electrodes and the Y electrodes. As explained so far, the plasma display device has various variations, and the present invention can be applied to each of them. 15 High-quality displays, which exceed the quality of CRT, require plasma display devices. Factors that will achieve high-quality display include high definition, high resolution (GRADATION), high brightness, high contrast, and so on. To achieve high definition, it is necessary to increase the number of display cells and lines by reducing the pitch. The ALIS method described above has a structure that enables high definition performance to be realized at low cost. To achieve high contrast, the intensity and number of discharges caused by the reset pulse must be reduced, not the display. To achieve a high stage, the number of sub-frames in the frame must be increased to increase the number of stage levels that can be represented, but this also requires reset actions and positions.

It is necessary to eliminate the problem of degradation of materials, and increase the number of times, but this will cause the number of times of electricity. In order to increase the number of sustain discharges, the reduction of the reset action and address movement must be shortened by the same rate as in the previous period or the duration of the sustain discharge needs to be shortened in the current structure. With its own, the stable appearance of the maintenance operation cycle needs to be maintained. Therefore, by taking 2: 2, because the time required for the sustain discharge operation is shortened to obtain a higher value: the operation with the address and the address are another method. With the relatively low brightness, the present invention relates to a type of shortened address. The female method required for the action is intended to increase the number of sub-frames in the frame: η: or to increase the rate of the maintenance cycle to achieve high brightness. In the conventional driving method described in Figure 3, When a scan pulse is sequentially applied to the pseudo electrode after a homogeneous state without wall charges is achieved by a reset action, an address signal is applied to the address electrode, and the trigger discharge and the surface discharge are in The wall charge that turns on the cell to perform and needs to emit light in the next maintenance action is formed. Therefore, one display line takes about 2 ys. For a panel with 500 lines, one address action takes 1 ms, and for a panel with 1,000 lines, it takes 2 ms. This means that the time required for the address action occupies most of the sequence and must be reduced. As described above, the address erasing method provides a state in which wall charges are uniformly maintained during the reset action and eliminates closed cells during the address action. Page 8 This paper applies Chinese National Standard (CNS) A4 specifications (210 X 297 mm) wall charge is performed and this method can shorten the time required to read the address. The load does not need to be formed by the mouth. 2 The narrow pulse balance system is applied. The operating boundary is very small, and the purpose of operating the system without invention is to achieve a more sustainable problem. The driving method of the display device of this work is stable enough. The motion is based on the wall power 2 purpose. The special operation of the driving method of the plasma display device of the present invention includes 2m of the work system, and the following 3 actions are left uniformly. In the selection action of the selected cell, one eliminates the wall electricity that performs the maintenance action in the selected cell. Two = Add to the electricity. One bit signal is sequentially applied to the address electrode in one scan pulse. , ^ Electrode) is used to perform the discharge of cells, because it is not similar to the conventional method of removing addresses, and because the entire ^ to form a wall charge, the time required to display the line is relatively short The time required is also short. In the next erasure action, erase. The wall charge selected to shut down the cell during the operation was no fault. For example, the second and second steps, a ramp pulse with a gradual change was applied, and the time for producing rain was short because the entire surface was at the same time. ^ Horvey at the time of the completion of the removal action 'after the reset action: why the cell is turned on and the wall charge of the closed cell is caused by the discharge / pulse system to be applied to the X electrode and the ΥElectrode between the electrodes is performed only on the turned-on cells to form the next maintenance action 第 9 页

Because the writing action can also be performed on the entire surface at the same time, the time required is short. With this writing action, The wall charge required for maintenance is formed in the on cell, no charge is maintained in the closed cell, and the maintenance action can be performed based on the display data without failure. In other words, the method for driving a plasma display according to the present invention is characterized in that: After the conventional address erasing method is executed, the erasing action and the writing action are increased to form a wall charge required to stably perform the next sustaining action. When the present invention is applied to the above-mentioned AL method method plasma In the display, the selection operation and the erasing operation can be performed in the same manner as the general electric indicator, but the writing operation is slightly different. In the writing operation of the odd figure 埸, a voltage is applied to the formation The x-electrode (first electrode: sustain electrode) and the γ-electrode (second electrode: scan electrode) of the display line of the odd-numbered figure are not applied between the even-numbered figure.

V. Description of the invention (?) Graphical illustration of waveforms printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs; and Figure 12 is a graphic illustration showing the frame structure of the driving sequence of the fifth embodiment of the present invention. Embodiments of the present invention are described below. The first embodiment 5 of the present invention is an example in which the present invention is applied to the conventional plasma display device of FIG. FIG. 4 is a diagram showing the driving waveforms of the first embodiment, that is, the driving waveforms in the second figure. 5A and 5B are diagrams showing changes in the charge on each electrode of the first embodiment. Please refer to FIGS. 5 and 5β as shown in FIG. 10, and the action performed by the driving waveform of FIG. 4 is described below. As shown in Fig. 4, a reset pulse of a large voltage Vw is applied to the Y electrode in a reset period. At this time, a voltage of 0V (ground level) is applied to the X electrode and the address electrode. By applying this reset pulse, the discharge is performed in all cells and wall charges are formed. Then, an oblique pulse of 15 strokes was applied. The wall charges are not completely neutralized at this time and a certain amount of wall charges are maintained symmetrically, as shown in Figures 5A and 5B. In this case, the positive charge is maintained on the X electrode and the negative charge is maintained on the γ electrode. The address period includes a selection period, an erasing period, and a writing period. In the selection period, the voltage Vs is applied to the X electrode and the γ electrode, and the scan pulse is sequentially applied to the γ electrode. The voltage can be reduced to 0 V, and in synchronization with this, the voltage Va The address signal is applied to an address electrode that turns off the cell.

On the other hand, in the on cell, discharge = is performed because no voltage is applied, and the same wall charges are maintained as those at the time of reset. All of the above are performed when the scan pulses are sequentially applied to all the scandium electrodes > 'positive charges accumulate on the " τγ' in all closed cells on the entire surface and negative charges accumulate On the address electrode. In this selection period, since it is not necessary to form wall charges by surface discharge, the scan pulse corresponds to its address signal can be shorter and the time required for the selection period is compared with the case where wall charges are formed by surface discharge. Get up short. Therefore, the amount of wall charges remaining on the cell after the discharge need not be so precise because these charges are completely eliminated in the next elimination cycle. In addition, since the voltage VS is applied to the X electrode adjacent to the γ electrode of the closed cell, the positive charge is moved to the Y electrode side and the negative charge is accumulated. However, the purpose of the discharge in the selection period is to form a wall charge (in this case, a positive charge) on the pseudo electrode by the discharge between the γ ′ electrode and the address electrode. Therefore, in The charge on this X electrode does not cause any problems. In the erasing period, when a voltage Vs is applied to the pseudo electrode, a ramp pulse whose voltage gradually decreases from the voltage Vs is applied to the X electrode. In this closed cell, the voltage of the wall charges accumulated on the X electrode and the γ electrode is placed on the oblique pulse during the day, resulting in a discharge and the wall charges are eliminated. As disclosed in the Japanese Unexamined Patent Publication (Kokai) No. 6-314〇78, even if the amount of wall charges accumulated on the X electrode and the γ electrode changes, it is necessary to apply Chinese national standards on page 13 of this paper (CNS) A4 specifications (210 X 297 mm) Μ -------- ^ --------- line ί Please read the precautions on the back before filling this page) 511057 A7 B7 Ministry of Economic Affairs Printed by the Intellectual Property Bureau's Consumer Cooperative. V. Invention Description (Η) It is possible to apply a ramp pulse to perform discharge without failure, and the wall charge in the closed cell is eliminated without failure. On the other hand, in the turned-on cell, because the voltage due to the wall charge has opposite polarity, the discharge is not performed and the same amount of wall charge is maintained as at the completion of the reset action. As described above, when the erasing action is completed, the same amount of wall charge as that at the time when the resetting action is completed is retained in the on cell, and the wall charge system in the off cell is eliminated. The obtuse waveform pulse balance is applied during the erasing period, but this can occur on the entire surface at the same time. Therefore, the erasing period is much shorter than the selection period. In this writing period, the voltage Vs is applied to the X electrode, the voltage OV is applied to the Y electrode, and the voltage Va is applied to the address electrode. By this, because the voltage caused by the same amount of wall charge as when the reset action is completed is superimposed, the discharge is performed by turning on the cell and the wall charge system required to maintain the action is formed. On the other hand, because there is no wall charge, the discharge system is not performed in a closed cell. Since the application of a pulse to each electrode in the writing period is performed on the entire surface at the same time, the writing period is much shorter than the selection period. The β address operation is performed by the selection and writing operations described above. As mentioned above, since the erase and write cycles are shorter than the select cycle, the time required for them can be ignored. In addition, it is possible that the scan pulse and the address signal to be applied in the erasing period can be pulses of a narrow width and can be completed in a shorter time than when wall charges are formed by surface discharge. In order to eliminate the scan pulses of the peripheral filaments and the width of the address signal, the wall charge formed in the closed cells changes in quantity, but the 5 10 15 20 page 14 ^ paper standards apply Chinese national standards ( CNS) A4 Specification ⑵G χ 297 Male Eding-II —I— II I--II — t * 111 11 11-$ 11 ^ 1 ^ (Please read the notes on the back before filling this page) Intellectual Property of the Ministry of Economic Affairs Printed by the Bureau ’s Consumer Cooperative 511057 A7 r -----___ B7 V. Description of the Invention (Q) Since the oblique pulse is applied in the elimination cycle, it is possible to perform the discharge without failure, and to close the wall in the cell The charge is eliminated without failure. In addition, the wall charges required for the sustain operation are formed without failure during the write cycle, and stable operation can be expected. 5 Fig. 6 is a diagram showing a driving waveform of a second embodiment of the present invention. This second embodiment is also an example in which the present invention is applied to a conventional plasma display device, and is different from the first embodiment in the oblique pulse, which is disclosed in Japanese Unexamined Patent Publication (Kokai) Case No. 2000-75835 is applied during the reset period, and a ramp pulse system that gradually rises from the ground level 10 to a voltage Vs is applied to the γ electrode, and the χ electrode is set to be connected during the elimination period. Position is accurate. By applying the ramp pulse ′ in the reset period, the amount of wall charges after the reset period can be arbitrarily adjusted by the voltage between the X electrode and the rhenium electrode when the application of the ramp pulse is completed. In this elimination cycle, although a gradually increasing oblique pulse system is applied to the ytterbium electrode as opposed to the first embodiment, the same effect can be achieved and the wall charges accumulated on the χ and γ electrodes even in the closed cell In quantitative changes, it is possible to perform the discharge without failure, and the wall charge in the shutdown cell is eliminated without failure.

Therefore, 2ll display lines are formed by (2η + 1) display electrodes. In other words, in the alis method, the display resolution is in It can be doubled with the same number of display electrodes as conventional PD devices. In addition, the discharge space can be used less wastefully, and a high opening ratio can be achieved and high brightness can be achieved because The amount of light blocked by these electrodes is micro 10 15 printed by the Intellectual Property Bureau employee consumer cooperative of the Ministry of Economic Affairs. The small odd X electrodes are driven by the odd X drive circuit 25 and the even X electrodes are driven by the even X drive circuit 26. The Y electrode is driven by a gamma scanning driver 22. The gamma scanning driver 22 includes a displacement register and a driving circuit. In the address operation, the driving circuit sequentially applies the scanning pulses generated by the displacement register. To this gamma Otherwise, the signal generated by the odd γ sustain circuit 23 is applied to the odd γ electrode and the signal generated by the even γ sustain circuit 24 is applied to the even γ electrode.

Description of the invention (/ 4 Electricity cannot be performed simultaneously. Therefore, the so-called separation Interlace scanning is performed, in which the display system is formed by odd and even lines in a time division form. In this ALIS method PD device, the formation between the n-th X electrode and the n-th electrode is performed. The display line, that is, as shown in FIG. 7, the display line formed between the γ electrode and the upper χ electrode is an odd display line, and is formed between the (η + 1) th χ electrode and the η The display lines between the electrodes, that is, as shown in FIG. 7, the display lines formed between the Υ electrode and the lower X electrode are odd-numbered display lines. In the odd-numbered graph 埸, the display system is established by the odd-numbered display line, and in the even-numbered graph 埸, the display system is established by the even-numbered display line, and the total display system of those in the odd-numbered graph 埸 and the even-numbered graph 埸 is obtained. As shown in Figs. 8 and 9, in the set period, the waveform system in the odd figure 埸 and the even figure 埸 is the same, and the ramp pulse system is applied in the reset period similarly to the second embodiment. Therefore, it is possible to adjust the amount of wall charge after the reset period by the voltage between the χ electrode and the γ electrode when the application of the ramp pulse is completed. In addition, the waveforms in the odd-numbered graph 埸 and the even-numbered graph 在 are the same in the selection period. Moreover, when the voltages of the X electrode and the γ electrode are set to a fixed value, the scan pulses of negative direction are sequentially applied. The potential of the gamma electrode is at the ground level and, in synchronization with this, an address signal is applied to the address electrode. The address signal is a pulse that applies a positive voltage to a cell that has no light emission and no pulse is generated to a cell that has light emission. This causes a discharge between the γ electrode and the address electrode in a cell without light emission, and a positive charge is accumulated on the γ electrode, as shown in Figure 5B. — — — — — — — — — — — I · 11!

Moreover, in the selection cycle of the third embodiment, it is not necessary to form wall charges by surface discharge, so these scans The pulses and those corresponding to them can be short and the time required for the selection cycle is short. Furthermore, the remaining wall charges in closing the cells need not be so precise, because these charges are completely eliminated by the next elimination discharge In the odd-numbered graph 埸 and the even-numbered graph 的, the address action is the same, and the distribution of wall charges on the Y electrode and the adjacent X electrode is the same, and there is no difference between the odd-numbered and even-numbered display lines. In the later writing cycle, whether the odd-numbered display line or the even-numbered display line is selected, the upper adjacent ones are selected. In the erasing period, similarly to the second embodiment, when the X electrode is set to the ground level, the The pulse, whose voltage is gradually increased from the ground level to the voltage VS, is applied to the γ electrode. This enables the discharge to occur without failure, even if it accumulates in the X of the closed cell The wall charge on the γ electrode changes in quantity, and the wall charge in the off cell is eliminated without failure. As shown in Figure 8, during the write cycle of the odd figure 埸, the voltage Va is applied To the address electrode, and in the first half of the period, the voltage Vs is applied to the odd X electrodes and the even γ electrodes, and the voltage OV is applied to the even X electrodes and the odd Y electrodes to generate the odd X electrodes and the odd Y electrodes.

This causes the discharge of the open cell between the odd χ electrode and the odd ¥ electrode, because the remaining wall charge voltage in the cell is the same as when the reset action was completed. The wall charges that are superimposed and required for sustaining action are formed on the odd χ electrodes and the odd γ electrodes. On the other hand, the discharge does not occur when the cell is turned off because there is no wall charge. — — — — — — — — — — — — 1 ^^ 1 — — — — — — ^ · 1111111 II (Please read the precautions on the back before filling this page) Page 18

5. Description of the invention (ί6) 5 At the time of attack, the discharge does not occur between the even X electrode and the even γ electrode, because the voltage of the wall charge has the opposite polarity to the one applied. Because no voltage is applied between the even X electrode and the odd υ electrode, and between the odd ^ electrode and the even γ electrode, no discharge occurs. In other words, in the first half of an odd-numbered write cycle, the wall charge required for the next sustain discharge is formed on an odd-numbered display line other than the odd-numbered display line, and the discharge does not occur outside the odd-numbered display line. Even-numbered display lines and even-numbered display lines. In the second half of the writing cycle of the odd figure 埸, the voltage Vs is applied to the even X electrodes and the odd γ electrodes, and the voltage ον is applied to the odd χ electrodes and the even Y electrodes to generate between the even χ electrodes and the odd γ electrodes. Intermittent write discharge B. This causes the discharge between the even χ electrode and the odd γ electrode in the cell to be turned on, because the voltage of the remaining wall charges in the cell is the same as when the reset action is completed, and the next sustain action is superimposed. The required wall charge is formed, but the discharge does not occur when the cell is turned off because there is no wall charge. Similarly, discharge does not occur on even-numbered display lines. When the above-mentioned writing cycle is completed, the wall charges required for the next sustain discharge are formed on the odd-numbered x electrodes and the odd-numbered γ electrodes forming the odd-numbered display lines, and on the even-numbered χ electrodes and the even-numbered γ electrodes. Since the application of the pulse to each electrode occurs simultaneously on the entire surface during the write cycle:, the write cycle is much shorter than the selection cycle. As described above, during the write cycle, the odd or even display lines are not reduced. Being chosen, it's a matter of choice. Then, in the sustain period, when sustains of opposite polarities are applied to a pair of odd-numbered x electrodes and even-numbered γ electrodes, and a pair of even-numbered X-electrodes ------------ IM ---- ---- ^ --------- ^ {Jingxian «Read the notes on the reverse side and then fill out this page) Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs page 19

511057 A7 V. Description of Invention (Π) 5 10 15 The 20-pole and odd-numbered Y-electricity are printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, and the transfer discharge occurs on the odd-numbered display line. As shown in FIG. 9, the waveforms in the reset period, selection period, and cancellation period of the even figure 埸 are the same as those in the odd figure 埸. In the writing cycle of the even figure 埸, the voltage Vs is applied to the even X electrodes and the even γ electrodes in the first half of the cycle, and the voltage OV is applied to the odd X electrodes and the odd γ electrodes to generate the even X electrodes The write discharge A to the odd-numbered γ electrode. This allows the wall charges required for the next sustain discharge to be formed on the odd display lines other than the odd display lines and the discharge does not occur on the even display lines other than the odd and even display lines. In the second half of the writing cycle of the even figure 埸, the voltage Vs is applied to the odd X electrodes and the odd Y electrodes, and the voltage OV is applied to the even X electrodes and the even γ electrodes to generate the odd X electrodes and the even γ electrodes. Write discharge B. This allows the wall charges required for the next sustain discharge to be formed on the even-numbered display lines other than the even-numbered display lines and the discharge does not occur on the odd-numbered display lines. When the above-mentioned write cycle is completed, the wall charges required for the next sustain discharge are formed on the even X electrodes and the odd Υ electrodes forming the even display lines and on the even χ electrodes and the odd γ electrodes. Similarly, since the application of the pulse to each electrode occurs simultaneously on the entire surface during the writing period, the writing period is much shorter than the selection period. In the following, the same action as that in the odd-numbered figure 维持 of the maintenance cycle occurs. In the third embodiment, regardless of the use of the ALIS method, the operations in the reset period, selection period, and cancellation period are the same in the odd-numbered graph 埸 and the even-numbered graph ，, and the difference between the odd-numbered display line and the even-numbered display line is The selection is completed in the writing cycle, but the selection between the odd and even display lines.

5 The printing of employee cooperatives by the Intellectual Property Bureau of the Ministry of Economic Affairs can be completed in the selection cycle. The fourth embodiment of the present invention is for the case where the selection between the odd-numbered display lines and the even-numbered display lines is performed in an ALIS method plasma display device. '' A plasma display device according to a fourth embodiment of the present invention has a structure similar to that of Fig. 7 and is driven by the driving waveforms shown in Figs. Fig. 10 shows the driving waveforms in the odd figure 埸, and Fig. 10 shows the driving waveforms in the even figure 埸. In the plasma display device of the fourth embodiment, the selection period is divided into a front half and a rear half and selection is completed. As shown in Fig. 10, in the selection cycle of the odd figure 埸, a positive voltage is applied to the X electrode, and in the first half of the cycle, the voltage V0 is applied to the even X electrode, and the scan pulses are sequentially Applied to the odd γ electrodes and in synchronization with this, the address signal is applied to the address electrodes. During this time, a positive voltage is applied to the even gamma electrodes. Then, a voltage of 0 V is applied to the odd-numbered χ electrodes, and in the second half of the period, a positive voltage is applied to the even-numbered X electrodes, and a scan pulse is sequentially applied to the even-numbered Υ electrodes, and in synchronization with this, the address signal system Apply to the address electrode. During this time, a positive voltage is applied to the odd chirped electrodes. This causes a discharge and positive charge accumulation on the γ electrode that turns off the cell, but the accumulation of negative charges due to the discharge on the X electrode side makes it more likely that the charges are accumulated on the χ electrode side that forms the odd display line, and On the X electrode forming the even digital display line. Therefore, the discharge in the case where the charge in the shutdown cell is eliminated during the elimination cycle becomes more likely to occur on the X electrode side forming the odd numbered display lines and the wall charge on the χ electrode side forming the even numbered display lines. Compared to the case of the third embodiment, the influence is reduced.

Fig. 12 is a diagram showing a frame structure in a driving sequence of a plasma display device according to a fifth embodiment of the present invention. In the first to fourth embodiments, 'the sub-pictures that construct a frame have a reset period, an address period, and a sustain period', respectively, as shown in FIG. 2. It is possible to provide only the reset period to the first field of each frame, and reset periods in other frames can be removed. In the plasma display device of the present invention, the address period includes a selection period, an erasing period, and a writing period. Therefore, the frame has a structure as shown in FIG. In the case of the driving sequence of the fifth embodiment, it is reduced irrespective of the number of reset cycles accompanying the light emission, and the display contrast is improved. As described above, according to the present invention, the address action can occur shortly and without interruption. Therefore, it is necessary to improve the display 7C degree by increasing the time of the maintenance cycle or by increasing the construction. Number to reach high
